Steps of the Scientific Method
Something you think might happen based on an observation.
What is an inference?
As y increases, x decreases.
what is y ∝ a/x?
A quantity that has a value which describes something.
What is a variable?
A mathematical diagram showing the relationship between two variables...
What is a graph
The format that a hypothesis is written in.
What is an if/then statement?
The first step of the Scientific Method
What is the research question?
As x increase, y increases
what is y ∝ x?
The dependent variable of the research question "How does salt change the freezing temperature of water?"
What is the freezing temperature of water?
Scientists make predictions based off these.
What is a pattern?
The relationship being studied in the hypothesis "If the length of the pendulum increases, then the period of the pendulum will increase"
The senses we use to make observations
What are touch, sight, taste, smell, and hearing?
Y varies directly with the square of x.
What is y ∝ ax2?
What is the independent variable of the research question "Does ultraviolet (UV) radiation affects skin cancer?"
What is UV radiation
When one variable increases, the other decreases.
What is an inverse relationship?
A hypothesis for the research question "How does sunlight affect plant growth?"
(Varies) If a plant gets more sunlight, then the plant will grow faster.
It is testable, open-ended, and drives the experiment.
As x increases, y stays the same.
What is y ∝ b?
The three main variables in an experiment
What are the IV, DV, and CVs?
The variable that is represented by the y-axis.
What is the Dependent Variable?
A hypothesis to the research question "How does mass affect the speed of a car?"
(Varies) If the mass of the car decreases, then the speed of the car will decrease.
The steps of the Scientific Method in order.
Research question, hypothesis, experiment, record and analysis data, draw conclusions, and report results.
Y varies inversely with the square of x.
What is y=a/x2?
The research question with the independent variable "speed" and the dependent variable "gas milage"
"Does speed affect gas mileage?"
The units of the y-axis divided by the units of the x-axis.
What are the units of the slope?
How does mass affect the period of the pendulum?
